  • STEREOTACTIC RADIOTHERAPY FOR HEAD AND NECK CANCERS WITH MICRO-MULTI-LEAF (m3)

説明

Head and neck tumors are located in complicated anatomical structures comprised by critical organs. These tumors were stereotactically treated with Micro-Multi-Leaf (m3TM) which can make fields encompassing targets. The subjects were 3 patieots with parotid tumors, 3 with maxillary sinus tumors, 2 with nasopharyngeal carcinomas, 2 with oropharyngeal carcinomas, and 1 each with ethmoid sinus, oral cavity, and nasal tumors. the subjects were immobilized with a shell and underwent CT scan of thin slices. Targets and risk organs of orbits, spinal cord, and parotid glands were marked on the CT images. Targets were defined with margins of 3mm from clinical tumors and were irradiated through 4-7 static non-coplanar portals. Doses of fractionated stereotactic irradiation were 2.5-4Gy daily and 15-62.5Gy in total. Peak doses of 102-112% of isocenter dose indicated remarkable flatness of dose distribution. Doses to risk organs of eyeballs, parotid glands, and spinal cord were acceptable.
